Help

Help I'm at the point in my life where I feel worthless and like I have no one. My mom says to go away and figure out how to stop stuttering when I try to talk to her. I might be getting disqualified due to my stutter in ROTC because it's gotten so bad, and I might be ruining my only chance at being a leader on campus (I finally got a job that I've applied and interviewed three times for before). Has anyone felt like this is the end? I have nowhere else to go. It's not like I'm trying to stutter.. It's almost as if people think I'm doing it on purpose to inconvenience them. Currently 20 and a college student.
